Description
(Visible only when parameter 22.220
Defines acceleration time 1 as the time required for the
speed to change from zero to the speed defined by
parameter 46.01 Speed scaling (not to parameter
Maximum speed).
Acceleration time 1.
(Visible only when parameter 22.220
Defines deceleration time 1 as the time required for the
speed to change from the speed defined by parameter
46.01 Speed scaling (not from parameter
speed) to zero.
Deceleration time 1.
Defines the time within which the drive stops if the drive
receives a Fast stop command (20.210 Fast stop
Fast stop deceleration time.
Speed error calculation; speed error window control
configuration; speed error step.
See the control chain diagram on page 498.
Displays the ramped and corrected speed reference
(before speed error calculation). See the control chain
diagram on page 498.
This parameter is read-only.
Speed reference used for speed error calculation.
Displays the speed feedback used for speed error
calculation. See the control chain diagram on page 498.
This parameter is read-only.
Speed feedback used for speed error calculation.
Displays the filtered speed error. See the control chain
diagram on page 498.
This parameter is read-only.
Filtered speed error.
Displays the inverted (unfiltered) speed error. See the
control chain diagram on page 498.
This parameter is read-only.
Inverted speed error.
Defines a speed reference correction, ie. a value added to
the existing reference between ramping and limitation.
This is useful to trim the speed if necessary, for example
to adjust draw between sections of a paper machine.
See the control chain diagram on page 498.
